Log temperatures for post analysis

MaracMB

Hello,
I am testing a bunch of things and would like to log and further analyse the data on temperatures in Excel

So how do i log and export temperature readings?

no built in function i'm affraid; which board and firmware version?

@bearer duet wifi+duex5 on latest fw 3

I thought there is somesort of debugging/logging function that generates log (m929 ?).
Would be nice if it just logged temperatures on sensors like every 0.5 or 1 second reading interval.. any extra parameters would be supercool.

Example #1
I am inserting a thermistor in a hemera’s heatsink. Just looking at DWC and logging stuff manually is a bad way of doing it. Log would show the gradual increase (or not) throughout a print.

#2
Ambient temperature in relation to buildspace temperature throughout a 24 hour print.

List goes on.

That would be very helpful stuff

I don’t have explicit coding skills, but friends do, so is there an API for this? So a separate service would just read and log from DWC?

m929 only logs start/stop of prints, so no good for graphing temps.

you could use daemon.g with M118 to send a message containing a object model refrence to serial or telnet, and collect the data there; or use M408 from serial or telnet to poll data from the duet - or M409 for a more targeted query of the object model

M111 enables debug info, not sure of contents and intervals - might affect operation but you could poke it and see what you find?

you can also query the duet with M408/M409 using HTTP, but in generall it'll be a bit of DIY i think,

tampermonkey to capture the temp graph from DWC might be an option; there have been a few other threads on the same topic, maybe search to see if I missed someting

@bearer thank you. At least i have some options now. I think tampermonkey would be best as it wouldn't load the duet at all. fan tastic

btw if you missed this, it might be of interest?

although the post wasn't clear if it would work with a duet2 running rrf3.2 or just a duet3 in standalone mode - the mention of dsf that runs on the sbc made it a bit confusing.

MaracMB

oooook... that confused the hell out of me.
i'm no expert but i guess this would then need raspberry pi and not sure if this even runs on Duet2... as you said. confusion is building up.

for a simple guy like me, tampermonkey is best bet.

tell me more about this thing you call sleep?:P

anyways, if you could share your work I'm sure others will appreciate it. as mentioned there has been a couple of similar threads recently. godspeed!

MaracMB

i edited/deleted because i thought you won't get it

i'll call my coding brain friend and will share if anything comes out of this.

Thank you for a very constructive debate.

Sorry for nagging, but could i get a link to an API for this for my programmer?
He said he’ll write in python. I guess that’s ok?

try the links in this thread?

@bearer found it. thank you
